Simon can you tell me your opinion on this.
I have IP4 about 2 months old, 4.3.5 is the only fw that was on the phone and I have no other shsh.
Now I have a tethered jailbreak and a couple of times my phone reboot while I was away from the PC and
I really wanted to 4.3.3 untethered jailbreak.
In your experience, can you tell me whether this is possible
and if it's worth a try?
Without any responsibility, just your opinion?

That's because you can only restore to 5.0. Even if you had the update option available you would get an error 3002 if you tried. You have to restore to 5.0 then restore your backup after to get your stuff back.

I found this when I tried to update via itunes. I then tried the restore (I had previously been on 5 and downed to 4.1 on my 3GS) and that didnt work either. I'm getting cant connect to apple servers if I have the cydia adjustment to hosts, and if I dont have that, I get the message that the device is not eligible for that firmware. Looks like I'm stuck on 4.1 forever. I have SHSH for 4.3.3 as well but that puts me into the infinite recovery loop, whether I use the stock 4.3.3 or the custom one.

I'm beginning to wonder if Apple has found some way to detect the redirection to Saurik's server. Because none of its working for me. It just refuses to go any further if the real Apple server cant be found.

Try doing what I said in post 968. Put the phone in DFU when restoring.

I did something i knew I shouldn't have: Tried downgrading a iPhone 4 from 4.3.5 to 4.3.3 without SHSH blobs saved (it was soo dang tempting to try) since there were a few "successful" attempts using this guide:

big mistake! .....i got through all the steps...except the final step where my custom 4.3.3 almost restores then goes to dfu loop/black screen. Do you know why? (you dont have to answer this ...i know your time is valuable) Real quesiton is what are my options? Is it possible for me to restore to a custom ios5 as I really need to keep the baseband the same? I tried restoring to stock 4.3.5 and custom ios5, but get nailed with error 3194. I use iReb so I can mount a custom ipsw. I believe that only shsh for 5.0 is saved (ecid: 000003D52E1D43F7) however, still cant seem to restore to custom ios5. Any ideas how I can unbrick this without updating the BB?

what does simon say?

thanks is advance bro.....its 2am, been trying for 3 hours and cant get it straight...

Reason: wanted to be more clear

There is no way to downgrade without SHSH. Any guides saying otherwise are all BS. Anyone who said they had success using one of those guides had SHSH but just didn't know it. You will need to restore to a custom 5.0.
To get past that 3194 error do this:
Open tiny umbrella
Click on advanced
deselect the box that says "set hosts to cydia on exit"
Close tiny umbrella and proceed with the restore.

I have official 5.0 on my verizon iphone4 and using windows7 64bit. I want to downgrade to 4.2.6 or 4.2.8. I have all the shsh's saved and they all show on Tiny Umbrella.... 4.2.6, 4.2.8, 4.2.9, 4.2.10. T.U. TSS srevice starts up with no problem. Put iphone4 (verizon) in DFU mode and start i-tunes. Restore goes well until the end when I get an ERROR (1). Hit T.U. Exit rcovery but it doesn't take me out of recovery mode. Tried RECBOOT and it kicks me out but recovery mode comes right back in. Put iphone in DFU mode and used fix recovery 4.3. That goes smoothly when when my phone reboots,... I get the "Emergency phone only" and with the recovery sign (USB cable pointing at itunes icon) in the background. Now I can't get out of that. That's as far as I get. I use the latest T.U. and i'm on the latest i-tunes...hmmm ...do I have to downgrade my itunes to 10.1.2.17 to make this work? Nope,...that didn't work either! Frustrated but not giving up! Any ideas???
